OTTAWA—Some families seeking foreign caregivers to look after their children or family members with a disability will be exempt from paying a $1,000 application fee. The federal government published new regulations around hiring foreign caregivers on Wednesday, following through on a budget promise to change a system many felt placed an unfair burden on lower income families. The $1,000 application fee to hire foreign workers had been implemented in 2014 to address abuses in the broader temporary foreign worker program.
